Description

  The present invention relates to a sock worn on a foot when wearing shoes.

  There are shoes that show your feet beautifully by showing your bare feet. Many of those shoes that fall into several types, such as pumps, mules and sandals, are for women.

  In general, it is less desirable to wear shoes with bare feet. First of all, sweat from the feet sticks to the inside of the shoe, which not only makes it uncomfortable, but also promotes the growth of mold and bacteria. Further, when the shoe material is hard or does not fit the shape of the foot, the shoe is likely to rub if the shoe is worn with bare feet. Also, the feet get cold in winter, which is undesirable for health.

  Wearing stockings reduces the problems caused by wearing shoes with bare feet, but is not always sufficient. For example, thin stockings contribute little to preventing shoe rubs.

  Therefore, very short socks called sneaker socks and ankle socks (hereinafter referred to as “sneaker socks”) are on sale. When worn, sneaker socks are so short that the ankle is exposed and only covers the sole, sides and half of the toe side of the instep. Therefore, for example, when the sneaker socks are worn and the pumps are worn, the sneaker socks are often generally hidden by the pumps.

  As so-called sneaker socks, gel socks that are worn indoors after bathing, for example, are being sold to moisturize the soles, sides and insteps of the toe side (for example, after bathing). Non-patent document 1).

  The gel socks described in Non-Patent Document 1 have almost the same shape as the sneaker socks, but a gel-like elastic material is used as a material, rose hip oil is infiltrated, and the foot moisturizes when worn. It is said that.

FIG. 2 is a cross-sectional view of a gel sock (for a right foot) according to an embodiment of the present invention cut from a plane perpendicular to the front-rear direction and viewed from the front side. FIG. 3 is a plan view of the gel socks (for the right foot) according to one embodiment of the present invention. FIG. 4 is a bottom view of the gel socks (for the right foot) according to one embodiment of the present invention.

(Example)
Hereinafter, an embodiment which is a specific example of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view schematically showing the appearance of a pair of left and right gel socks 1 according to the present embodiment, and FIG. 2 is a plane perpendicular to the front-rear direction of the gel socks 1 for right foot according to the present embodiment. It is sectional drawing seen from the front side by cutting in.

  FIG. 3 is a plan view of the right foot gel socks 1 according to this embodiment as viewed from above, and FIG. 4 is a bottom view of the right foot gel socks 1 according to this embodiment as viewed from below. .

  As shown in FIG. 1, the shape of the gel socks 1 has an opening on the upper side for the user to put his / her foot in the same manner as a normal sneaker sock, It has a shape that covers the instep and sole of the foot. The gel socks 1 have moderate elasticity, and when the user wears the gel socks 1 having a size slightly smaller than the size of his / her feet, the gel socks 1 fits the user's feet.

  The gel socks 1 include an inner sheet portion 11 that is a sheet-like body forming an inner surface, an outer sheet portion 12 that is an outer surface and is harder than the inner sheet portion 11, and the inner sheet portion 11 and the outer sheet. An internal gel portion 13 that is a gel-like body enclosed between the portion 12 and the portion 12 is provided.

  The inner sheet portion 11, the outer sheet portion 12, and the inner gel portion 13 are all made of a thermoplastic elastomer. Elastomer is a general term for industrial materials having rubber-like elasticity.

  However, each of the inner sheet portion 11, the outer sheet portion 12, and the inner gel portion 13 is made of a different material among the above-mentioned elastomers because of different usage purposes and conditions.

  Since the inner sheet portion 11 directly touches the user's foot when worn, the material is preferably a thin and soft material. In addition, if the inner sheet portion 11 is thin and soft, the inner gel portion 13 is not so hindered from fitting to the details of the foot, and the user can feel the soft feel of the inner gel portion 13 and is comfortable to wear.

  As a material having such characteristics, in the gel socks 1, for example, soft silicon rubber is adopted as the material of the inner sheet portion 11.

  Since the outer sheet portion 12 touches the shoes when wearing the shoes, the outer sheet portion 12 needs to be strong enough not to be easily damaged by rubbing with the shoes accompanying walking or the like. In addition, when the shoe is worn, if the frictional resistance between the shoe and the shoe is large, there is a problem that the foot does not easily enter the shoe or the foot is difficult to come off from the shoe when the shoe is taken off. Therefore, it is desirable that the material of the outer sheet portion 12 is a material having higher strength than the inner gel portion 13, hard, less deformed, and easy to slip on the surface.

  As a material having such characteristics, in the gel socks 1, for example, silicon rubber harder than the material of the inner sheet portion 11 is used as the material of the outer sheet portion 12.

  The internal gel portion 13 serves as a cushioning material between the user's feet and shoes. The internal gel portion 13 allows the user to feel a comfortable fit when wearing the gel socks 1 and to protect the foot from rubbing with the shoes during walking.

  Further, the inner gel portion 13 absorbs a shift generated between the outer sheet portion 12 that contacts the shoe and follows the movement of the shoe, and the inner sheet portion 11 that contacts the foot and follows the movement of the foot. No local stress is generated in the portion 12 and the inner sheet portion 11, and they also serve to make them difficult to break.

  In the gel socks 1, for example, a silicon gel mixed with sodium polyacrylate as a cold insulating agent or a heat insulating agent is used as a material of the internal gel portion 13.

  Since the internal gel portion 13 is mixed with a cold-retaining agent and a heat-retaining agent, the user wears the gel socks 1 warmed in the winter and the gel socks 1 cooled in the summer, so that the comfort immediately after wearing the gel socks 1 Can feel.

  The inner sheet portion 11, the outer sheet portion 12, and the inner gel portion 13 all have high light transmittance (that is, almost transparent), and the total light transmittance of these three layers is, for example, 90% at any portion. That's it. Therefore, when the user puts on the gel socks 1, and then wears pumps, mules, sandals, etc., even if a part of the gel socks 1 is visible on or between those shoes, the appearance of the gel socks 1 is not greatly impaired. Absent.

  Since the gel socks 1 are worn in shoes for outer wear and are supposed to be worn for a long time, it is necessary to prevent the feet from becoming damp inside the gel socks 1. Therefore, the gel socks 1 are provided with a large number of ventilation holes 14 having a diameter of about 1 millimeter (not shown in FIGS. 1, 3 and 4). As shown in FIG. 2, the vent hole 14 penetrates the inner sheet portion 11, the inner gel portion 13, and the outer sheet portion 12, and releases vapor evaporated from the foot to the outside.

  The thickness of the inner sheet portion 11 is, for example, 0.2 mm.

  From the viewpoint of comfort, it is desirable that the gel socks 1 be as thin as possible. On the other hand, it is desirable that the gel socks 1 be as thin as possible from the viewpoint of shoe rub prevention and strength. In order to balance the gel socks 1, the part where the shoe and the foot are rubbed, specifically the part covering the sole of the foot excluding the heel, the toe, and the arch (the hatched area in FIGS. 3 and 4). The outer sheet portion 12 and the inner gel portion 13 are thicker and stronger than the other portions.

  More specifically, the thickness of the outer sheet portion 12 in the portion covering the sole of the foot excluding the heel, toe, and arch is, for example, 0.8 millimeters, and the thickness of the outer sheet portion 12 in the other portions is, for example, 0. .3 millimeters. Further, the thickness of the internal gel portion 13 in the portion covering the sole of the foot excluding the heel, toe, and arch is, for example, about 1.0 mm, and the thickness of the internal gel portion 13 in the other portion is, for example, 0.5 mm. It is. However, since the inner gel part 13 moves freely between the inner sheet part 11 and the outer sheet part 12, the thickness varies depending on the shape of the user's foot when worn.

  Therefore, the thickness of the entire three layers of the inner sheet portion 11, the outer sheet portion 12, and the inner gel portion 13 is approximately 2.0 millimeters in the portion covering the sole of the foot excluding the heel, toe, and arch, In the part, it is about 1.0 millimeter.

  The gel socks 1 having the configuration as described above are used in the same manner as ordinary sneaker socks except that they can be used by being heated or cooled as necessary. At that time, the rubbing of shoes is effectively prevented, and since it is transparent, even when wearing shoes with many exposed portions of bare feet such as pumps, mules, and sandals, the aesthetic appearance is not greatly impaired.

  In addition, the gel provides a comfortable fit and ensures breathability, so the foot does not get much steamed compared to normal socks.

(Modification)
The embodiment described above can be variously modified within the scope of the technical idea of the present invention. Examples of these modifications are shown below.

  First, the numerical value, shape, material, number, position, etc. for specifying the configuration of the gel socks 1 described above are merely examples, and other values, shape, material, number, position, etc. are used unless there is a particular problem. Also good.

  For example, although the gel socks 1 described above have the same shape as the sneaker socks, the present invention is not limited in that respect, and may have other shapes such as normal socks or high socks.

  Moreover, although the gel socks 1 described above have a shape in which the finger portion is not separated, for example, the gel sock 1 may have a shape in which a gap is provided between the thumb portion and the index finger portion. The gel socks having such a shape can be used when a user wears a sandal with a snare or the like.

  In the gel socks 1 described above, the inner sheet portion 11, the outer sheet portion 12, and the inner gel portion 13 are all made of a thermoplastic elastomer, and more specifically made of silicon rubber. However, the present invention is not limited thereto and may be made of other elastic materials such as non-thermoplastic elastomers.

  Further, in the gel socks 1 described above, the thickness of the outer sheet portion 12 and the inner gel portion 13 in the portion covering the sole of the foot excluding the heel, the toe, and the arch is thicker than the thickness of the other portion and the strength is increased. However, the portion that is thicker and stronger than the other portions is not necessarily limited to the portion that covers the sole of the foot except the heel, toes, and arch. For example, of the parts covering the instep, heels, soles of the feet, toes, and little toes, an appropriate part that is likely to cause shoe rubbing is selected, and that part is thicker than the other parts. It is desirable that the strength is higher than other parts. If there is no particular problem, the thickness of the gel socks 1 may not be changed and may be uniform as a whole.

  Moreover, the thickness of the inner sheet | seat part 11, the outer sheet | seat part 12, and the internal gel part 13 of the gel socks 1 mentioned above is a design matter which can be changed freely.

  In the gel socks 1 described above, the light transmittance of the entire three layers of the inner sheet portion 11, the outer sheet portion 12, and the inner gel portion 13 is 90% or more. The transmittance may be 70% or more. Further, it is not necessary to ensure high light transmittance in the entire region of the gel socks 1, and for example, the sole of the foot that does not affect the appearance may be made of an opaque material. That is, the portions where high light transmittance should be ensured are the portions that cover the left and right side surfaces of the foot, the top of the foot, the top surface of the toe, and the heel.

  Further, in the gel socks 1 described above, the vent hole 14 having a diameter of 1 millimeter is provided throughout, but the present invention is not limited thereto, and the vent hole 14 having a diameter other than 1 millimeter is provided. Alternatively, the region where the vent hole 14 is provided may be a partial region of the gel socks 1. Moreover, you may ensure a ventilation hole by making the gel socks 1 whole or one part mesh shape.

  In addition, the gel socks 1 described above includes sodium polyacrylate as the cryogen / heat retention agent in the internal gel portion 13, but the present invention is not limited thereto, and for example, a cryogen / heat retention agent other than sodium polyacrylate is present. These materials may be used, and those cold-retaining agents and heat-retaining agents may be mixed in the material of the inner sheet portion 11 and the outer sheet portion 12. Further, no cryogen or heat insulating agent may be used.

  The present invention can be widely used by female general consumers in order to provide a sock that is comfortable to wear and prevents rubbing of shoes and does not impair the beauty of shoes. Therefore, it is manufactured and sold in large quantities and can be used in service industries such as so-called manufacturing and retailing.
